Abstract: For a complex connected semisimple linear algebraic group G of adjoint type and of rank n, De Concini and Procesi constructed its wonderful compactification \bar{G}, which is a smooth Fano GxG-variety of Picard number n enjoying many interesting properties. In this talk, we will show that the wonderful compactification \bar{G} is rigid under Fano deformations. Namely, for any family of smooth Fano varieties over a connected base, if one fiber is isomorphic to
\bar{G}, then so are all other fibers. This is a joint work with Qifeng LI. |
